Freshwater Aquaculture Center

Phillipines



Site/Facility


Site Status: Active Companion Site; 1992 - present

General Description: FAC is a semi-autonomous unit in the University, loosely linked with the Research, Extension and Training Unit (RET) of CLSU in its organizational and management structure, such that RET only monitors FAC's activities. FAC is a separate unit parallel in status to the College of Fisheries (CF). At present the two units are sharing technical staff and facilities. The total work force is 60. The senior staff (14) devote half of their time to research at the Center and the other half to academic duties in the CF and Department of Aquaculture, Institute of Graduate Studies. Pond facilities include 98 earthen ponds ranging in size from 400 to 2500 m2. Twelve 500 m2 ponds are assigned to the CRSP research program. Additional ponds are being used by the University College of Swansea-FAC Project on "YY-GMT"; another 8 ha are used as ICLARM-BFAR-CLSU "GIFT" breeding facilities, and there is a rice-fish experimental area. There are numerous concrete and fiberglass tanks and a hatchery/wet lab building. The Center maintains laboratories equipped with facilities and equipment for fish physiology, soil and water quality analytical chemistry, fish pathology, fish nutrition, and feed development.

Relative location: FAC is located at the northeastern most extension of Central Luzon State University, 1.5 km from the main university campus. CLSU is 3.5 km northeast of the town of Munoz, in the province of Nueva Ecija. Munoz is approximately 150 km north of Manila, and lies in the heart of the central valley of Luzon, which is the rice bowl of the Philippines.

Latitude and longitude: 15 43'N and 120 54'E

Elevation: 30 m 

Water Supply: Water comes to the station through open canals from the 8420-ha Pantabangan Reservoir, which is located about 30 km from the FAC. Two deep wells and six shallow wells provide additional water for the Center.

Soils: Pond soils at the FAC have very high clay contents, with an average of 62.5% for the ponds used in CRSP experiments. In 1993 the mean CEC for the CRSP ponds was 38.8 meq/100 g; exchangeable base measurements were 23.7, 14.5, and 1.1 meq/100 g for Ca, Mg, and Na, respectively. The soils are alkaline, with base saturation values of 100% and an average pH of 7.6.

 

Area/Region

Climate: Köppen classification Aw: Humid tropical group (A), tropical wet-and-dry type (w).

Temperatures: The average annual temperature in the province of Nueva Ecija is 27.8°C. In 1995 the maximum and minimum air temperatures at the FAC were 35.5 and 23.1°C, respectively.

Precipitation: Average annual rainfall in the province is about 2250 mm. Most of the rainfall occurs between the months of May and October.

Humidity: Mean annual relative humidity is normally in the range of 74 to 78%. It is hot and dusty from March to May.

Seasonality: There are two distinct seasons in this part of the Philippines. The dry season begins in about December and lasts through April or May, and the rainy season begins in June and continues through November.

Topography: The central valley is a vast, relatively flat lowland that stretches approximately 150 km from Manila Bay in the south to the Lingayen Gulf on the western coast of Luzon. The elevation of most of this lowland area is less than 40 m. The Zambales Mountains flank the plain to the west, while the Sierra Madre range lies on its eastern side.

Geology and Soils: The Philippines archipelago is part of a major western Pacific seismic fault system. The entire region is characterized by active volcanoes (12 of them in the Philippines), and all of the Philippine islands are subject to occasional earthquakes. Many of the peaks of the rugged mountains that make up the Philippine islands are dormant or extinct volcanoes. Soils in the central valley of Luzon are largely alluvial, clayey, and alkaline.

Linkage

The Center has more than ten PC's, and the e-mail and FAX machines of the UCS-FAC project are available for use by other FAC staff. Eight to twelve local and international graduate students conduct their research at the FAC each year. Improved breeds of tilapia, carp, and catfish, feeds and fertilizers, and labor for pond operation and maintenance are always readily available. PD/A CRSP
